"Russell Haswell (UK) and Yasunao Tone (Japan) have a rich history in exploring the extremes of sound and technology, where they intertwine and where the potential lies for deviation from the function intrinsic to their design. Both artists have undertaken years of rigorous exploration of sonic phenomena via the production of music tools. The constant shift in synthesis and production over the decades has only provoked further challenges resulting in an excited means of exploration and consistently new and challenging results. Over the course of his practice Haswell has disentangled the limits of Digital Audio Tape (DAT), the Sound Designer II software, Xenakis' UPIC system and analogue synthesis systems in a relentless pursuit of the new in the known. Yasunao Tone's audio investigations have regularly placed him within the systems and processes he has developed to generate works. His Wounded CD works and his interactions with data entry and software interfaces, such as graphic tab lets in 495.63 (2007) and his MP3 Deviation software employed on this release all provide a path whereby the human input creates a juncture in the 'normal' operations of the tools at hand. Convulsive Threshold forms a dialogue which sees two of the most recalcitrant sound artists active today coming together as one. CD release packaged in LP sleeve." (label info)
